Developmental trajectories of aggression from late childhood through adolescence: similarities and differences across gender

Although numerous investigations of overt aggressive and antisocial trajectories have been undertaken, there is a dearth of literature examining gender differences and similarities in trajectory patterns and their correlates. To address these gaps, we investigated gender differences in the prevalence rates, predictive validity during transition to adulthood, childhood risk factors, and adolescent correlates of different trajectories of teacher-reported overt aggression (i.e., fights, argues, gets in trouble) among 220 participants (116 girls and 104 boys) evaluated annually from grade 4 to grade 12. Four patterns of trajectories were identified: low, increasing (i.e., adolescent-onset), decreasing (i.e., childhood-limited), and high (i.e., childhood-onset). A large proportion of youth, particularly girls, displayed low levels of aggression over time. A small proportion followed the childhood-onset trajectory. Across gender, the childhood-onset trajectory was associated with the highest rates of maladjustment during the transition to adulthood, the highest number of childhood risk factors, and multiple problems during adolescence. The adolescent-onset trajectory was associated with few childhood risk factors, but with high levels of independent status during adolescence. In contrast, the childhood-limited trajectory was associated with several childhood risk factors, but high levels of parental monitoring and school engagement during adolescence. Romantic involvement differentiated the adolescent-onset and childhood-limited trajectories among girls.     

Beliefs About Cognitive Gender Differences: Accurate for Direction, Underestimated for Size

Although stereotype accuracy is a large, and often controversial, area of psychological research, surprisingly little research has examined the beliefs people have about gender differences in cognitive abilities. This study investigates the accuracy of these beliefs in a sample of 106 highly educated U.S. adults. Participants provided estimates of male and female performance for 12 cognitive tasks and games. These estimates were compared with published data on gender differences on the same 12 cognitive tasks and games. Results showed that participants were generally accurate about the direction of gender differences, but underestimated the size of gender differences.     

From Pink Frilly Dresses to ‘One of the Boys’: A Social‐Cognitive Analysis of Gender Identity Development and Gender Bias

In middle childhood, many girls go through a curious metamorphosis, in which their earlier embrace of all‐things‐feminine appears to transform into an identity as a tomboy. We believe this striking shift, observed in girls but not boys, signifies a critical development in children’s socio‐cognitive functioning, with implications for their understanding of gender as it relates to their identity and their social relationships. In this article, we review the evidence for this identity shift and present a theoretical account that integrates ideas from social cognition and social development. We argue that this identity shift involves the emergence of public regard and status awareness, with concurrent increases in the complexity with which knowledge associated with gender categories is represented in the mind. We then posit that these changes have important implications for the developmental trajectory of implicit and explicit gender attitudes and stereotypes, and we present a set of predictions generated by our theoretical analysis.     

Quality of Life Assessment for Physical Activity and Health Promotion

Despite the clear relationship of physical activity and quality of life (QoL), QoL measures are seldom targeted for physical activity and health promotion. The current research attempted to address that gap by developing a QoL measure based on a conceptual model that reflects positive health and is relevant for physical activity and health promotion programs. In the project, which extended over three phases, an initial 70-item QoL survey was administered to university students and community program participants (total n = 512) along with measures of satisfaction with life and physical activity. Exploratory and confirmatory factor analyses revealed clear social, emotional, cognitive, physical, spiritual and functional (ADL) QoL factors as well as integrated QoL. The resulting 32-item QoL Survey fits the conceptual model, demonstrates logical relationships with physical activity and has sufficient psychometric properties for use in related research and health promotion programs.     

The two-word stage: Motivated by linguistic or cognitive constraints?

Child development researchers often discuss a "two-word" stage during language acquisition. However, there is still debate over whether the existence of this stage reflects primarily cognitive or linguistic constraints. Analyses of longitudinal data from two Deaf children, Mei and Cal, not exposed to an accessible first language (American Sign Language - ASL) until the age of 6 years, suggest that a linguistic constraint is observed when cognition is relatively spared. These older children acquiring a first language after delayed exposure exhibit aspects of a two-word stage of language development. Results from intelligence assessments, achievement tests, drawing tasks, and qualitative cognitive analyses show that Mei and Cal are at least of average intelligence and ability. However, results from language analyses clearly show differences from both age peers and younger native signers in the early two-word stage, providing new insights into the nature of this phase of language development.     

Stability of language in childhood: a multiage, multidomain, multimeasure, and multisource study

The stability of language across childhood is traditionally assessed by exploring longitudinal relations between individual language measures. However, language encompasses many domains and varies with different sources (child speech, parental report, experimenter assessment). This study evaluated individual variation in multiple age-appropriate measures of child language derived from multiple sources and stability between their latent variables in 192 young children across more than 2 years. Structural equation modeling demonstrated the loading of multiple measures of child language from different sources on single latent variables of language at ages 20 months and 48 months. A large stability coefficient (r = .84) obtained between the 2 language latent variables. This stability obtained even when accounting for family socioeconomic status, maternal verbal intelligence, education, speech, tendency to respond in a socially desirable fashion, and child social competence. Stability was also equivalent for children in diverse childcare situations and for girls and boys. Across age, from the beginning of language acquisition to just before school entry, aggregating multiple age-appropriate methods and measures at each age and multiple reporters, children show a strong stability of individual differences in general language development.     

Moving Knowledge into Action: Developing the Rapid Synthesis and Translation Process Within the Interactive Systems Framework

The Interactive Systems Framework (ISF) for Dissemination and Implementation presents an overall framework for translating knowledge into action. Each of its three systems requires further clarification and explanation to truly understand how to conduct this work. This article describes the development and initial application of the Rapid Synthesis and Translation Process (RSTP) using the exchange model of knowledge transfer in the context of one of the ISF systems: the Prevention Synthesis and Translation System (see [special issue “introduction” article] for a translation of the Wandersman et al. (Am J Community Psychol 41:3–4, 2008) article using the RSTP). This six‐step process, which was developed by and for the Division of Violence Prevention at the Centers for Disease Control and Prevention in collaboration with partners, serves as an example of how a federal agency can expedite the transfer of research knowledge to practitioners to prevent violence. While the RSTP itself represents one of the possible functions in the Prevention Synthesis and Translation System, the resulting products affect both prevention support and prevention delivery as well. Examples of how practitioner and researcher feedback were incorporated into the Rapid Synthesis and Translation Process are discussed.

Reflective family play: A model for whole family intervention in the infant and preschool clinical population

This article proposes a new treatment model, Reflective Family Play, for clinical intervention in two‐parent families of children aged 0 to 5 years. It is play‐based and grounded in the evidence‐based treatment approach of Watch Wait and Wonder (WWW) as well as the assessment tool known as the Lausanne Family Play paradigm (LFP). WWW is a dyadic treatment for caregivers and their infants or preschoolers that has been shown to shift attachment in the very young (N.J. Cohen, E. Muir, & M. Lojkasek, 1999; N.J. Cohen, M. Lojkasek, E. Muir, R. Muir & C.J. Parker, 2002). The LFP is a more recent adaptation of the Lausanne Trilogue Play paradigm (LTP; E. Fivaz‐Depeursinge & A. Corboz‐Warnery, 1999). Together, the LTP/LFP have now been used for over 2 decades as reliable measures of the family alliance and interactions in two‐parent households. By combining concepts from WWW and the LTP/LFP, a novel approach is presented for treatment in two‐caregiver households. Clinical excerpts are used to illustrate.     

The effect of study time distribution on learning and retention: a Goldilocks principle for presentation rate

In 2 experiments, we investigated the effect of presentation rate on both immediate (5 min) and delayed (2 days) cued recall of paired associates. Word pairs were presented for a total of 16 s per pair, with presentation duration of individual presentations varying from 1 to 16 s. In Experiment 1, participants studied word pairs with presentation rates of 16 × 1 s, 8 × 2 s, 4 × 4 s, 2 × 8 s, or 1 × 16 s. A nonmonotonic relationship was found between presentation rate and cued recall performance. Both short (e.g., 1 s) and long (e.g., 16 s) presentation durations resulted in poor immediate and delayed recall, compared with intermediate presentation durations. In Experiment 2, we replicated these general findings. Moreover, we showed that the 4 s condition resulted in less proportional forgetting than the 1 s and the 16 s conditions.     

Family members' unique perspectives of the family: examining their scope, size, and relations to individual adjustment

Using the McMaster Family Assessment Device (Epstein, Baldwin, & Bishop, 1983) and incorporating the perspectives of adolescent, mother, and father, this study examined each family member's "unique perspective" or nonshared, idiosyncratic view of the family. We used a modified multitrait-multimethod confirmatory factor analysis that (a) isolated for each family member's 6 reports of family dysfunction the nonshared variance (a combination of variance idiosyncratic to the individual and measurement error) from variance shared by 1 or more family members and (b) extracted common variance across each family member's set of nonshared variances. The sample included 128 families from a U.S. East Coast metropolitan area. Each family member's unique perspective generalized across his or her different reports of family dysfunction and accounted for a sizable proportion of his or her own variance in reports of family dysfunction. In addition, after holding level of dysfunction constant across families and controlling for a family's shared variance (agreement regarding family dysfunction), each family member's unique perspective was associated with his or her own adjustment. Future applications and competing alternatives for what these "unique perspectives" reflect about the family are discussed.
